Keep in mind you might need to adjust INITIAL_CLUSTER_STATE too. Is there any workaround for this? Can you try editing the etcd-scripts ConfigMap adding the line below in the script? Check the container documentation to find all the ways to run this application. We just released a new major version of the etcd chart (6.0.0) including new features and introducing changes in the etcd that attempt to improve the stability of the chart on operations such as scaling or updating the etcd cluster, see the link: We also improve the docs, and create a specific section that explains details about how this chart works on operation such as bootstrapping or scaling (not available in the doc system yet), see. Launch in Bitnami Launchpad. Subscribe to project updates by watching the bitnami/etcd GitHub repo. Have a question about this project? On Microsoft Azure, you can launch this configuration into your account using the Microsoft Azure Marketplace. I like the idea, but it can be quite challenging to do so unless we provide the container the capabilities and RBAC permissions to talk with the K8s API to discover this information. The name of a single datastore on which etcd backup needs to be stored i.e. Helm charts. Could you try re-installing the chart using the latest chart version? We restarted everything and again we had an "empty" database. drwxrwsrwx 2 root root 4096 Jul 16 07:40 .

I tried to create a volume with a nfs mount, which has my etcd backups, instead of creating a new volume and copying files into that, but etcd doesn't find the files. Getting started with Etcd packaged by Bitnami container, Bitnami's Best Practices for Securing and Hardening Helm Charts, Backup and Restore Apache Kafka Deployments on Kubernetes, Backup and Restore Cluster Data with Bitnami and Velero, Docker Compose is recommended with a version 1.6.0 or later. Run the restore-snapshot command in all pods. Why does etcd not release this mount after a successful restore, so I can delete the pv,pvc. Hello @alemorcuq, do you have any update about this issue? I am having a similar issue, I have the same environment as @dk-do. The text was updated successfully, but these errors were encountered: I believe we could be running into something similar in our deployments on helm chart version 6.2.0. If that's not the case, then this can be considered another bug to be fixed. ReadOnly: false, Upon trying to restore ETCD, a new etcd-snapshotter pvc is created, which is by default empty, and no restore is triggered, and the pods are stuck in ContainerCreating. When updating the initialClusterState to "existing", the pod should rejoin the cluster and be able to recover from pod crash. If the cluster permanently loses more than (N-1)/2 members, it tries to recover the cluster from a previous snapshot. Get this image The recommended way to get the Bitnami Etcd Docker Image is to pull the prebuilt image from the Docker Hub Registry. I mean, I can't think of a way for the container (without consulting the K8s API) to know if the detected persisted data should be discarded or not. The above output is from kubectl exec-ing into a member in the cluster where we were observing this issue, and was consistent across all members of our 5 member cluster. haproxytech/ helm-charts on GitHub kubernetes-ingress-.7.2 Create a pod with some container that does nothing (e.g. etcd is widely used in production on account of its reliability, fault-tolerance and ease of use. Vulnerabilities scanner. The init-snapshot is only ever required for the initial restore right? As you can see in these lines (https://github.com/bitnami/charts/blob/master/bitnami/etcd/templates/statefulset.yaml#L131-L138), by default it's set to "new" when running helm install, while it's set to "existing" when running helm upgrade. That seems to be the issue here. Type: PersistentVolumeClaim (a reference to a PersistentVolumeClaim in the same namespace) Sometimes the restore is working. Yes, I don't think the member_id being empty is ever expected, @jaspermarcus. Note: Following the suggested remediation steps in #3190 (comment) did temporarily address the immediate issue, but it manifested in the same way a few days later. . When leaving the initialClusterState: "new" (or not setting it), pods crashing are not recovering. You signed in with another tab or window. Download virtual machines or run your own etcd server in the cloud. helm/ bitnami-aks/ redis on Artifact Hub 9.3.3 . You might want to try bitnami/bitnami-docker-etcd#21.

ETCD_INITIAL_CLUSTER changes from listing 5 node URLs to 3. I'll try to review the PR created by @ckoehn today and hopefully we should have a solution for this race condition during the week. Your Application Dashboard for Kubernetes, Unlock your full potential with Kubernetes courses designed by experts, Invest in your future and build your cloud native skills. It's so weird. etcd is a distributed key-value store designed to securely store data across a cluster. Maybe you can find something interesting in this list. I don't feel comfortable having the pv permanently mounted inside the pods, if they are not required. Everything went smooth. We should be able reuse the volume used by etcd-snapshotter to restore the cluster too. Launch a new Etcd packaged by Bitnami instance. Describe the bug I have provided a RWX volume for the snapshotter that is mounted in all etcd pods, I have confirmed that it is mounted in my new test cluster. To start using any Bitnami Helm chart, it is necessary to first add the Bitnami Helm chart repository to Helm and then run the helm install command to deploy this chart. I'm a little bit confused Could you please share the exact commands you used? Thanks in advance! Thanks for reporting. On 6. After killing one of the etcd pods, I think it was the -0 pod, this got into a crash loop: While pod -0 was still crashing with the above error, I tried to scaling down the entire statefulset to 0 with kubectl scale sts {name} --replicas=0, then back to 3. to your account. This Issue has been automatically marked as "stale" because it has not had recent activity (for 15 days). kubectl exec -it etcd-0 -- etcdctl snapshot restore /tmp/db --name etcd-0 --initial-cluster etcd-0=http://etcd-0.etcd-headless.default.svc.cluster.local:2380,etcd-1=http://etcd-1.etcd-headless.default.svc.cluster.local:2380,etcd-2=http://etcd-2.etcd-headless.default.svc.cluster.local:2380 --initial-cluster-token etcd-cluster-k8s --initial-advertise-peer-urls http://etcd-0.etcd-headless.default.svc.cluster.local:2380, COPY the restored data from /opt/bitnami/etcd/etcd-0.etcd/member/snap/db to the default data directory: /bitnami/etcd/data/member/snap/, Unfortunately it is not possible to change the data dir to the original restore location, because it contains the pod-id in the path: /opt/bitnami/etcd/etcd-0.etcd/member/snap/db. We have some issues regarding etcd-backup restores on Kubernetes: This method involves the following steps: Use the etcdctl tool to create a snapshot of the data in the source cluster. Not sure why it wasn't working for me the first few tries, my helm install command isn't soo much different. Those containers use images provided by Bitnami through its test & release pipeline and whose source code can be found at bitnami/containers.. As part of the container releases, the images are scanned for vulnerabilities, here you can find more info about this topic. `sleep infinity) and mount the PV on it. Improve this page by contributing to our documentation. @alemorcuq Is there a rough estimate when this will be worked on? Do you mean that I can try re-testing from the PR while trying to scale down/up through helm update instead of triggering it manually? I have just raised the internal priority of this issue. I will add it to the task. It seems overkill that I have a volume for each etcd instance, a volume to snapshot the cluster, and another volume to restore? Thanks for you assistance. Could it ever be expected that the member_id file is created, but empty? Cluster name to perform Backup/Restore on. Every single detail you mentioned is actually true!! I spun up a fresh cluster with 5 pods, deleted two pods randomly to test HA capabilities and now those two etcd pods are not recovering, i.e. Create the cluster. See https://github.com/bitnami/charts/blob/master/bitnami/etcd/README.md: Maybe we need some best practise advice how to solve the following issues: etcdctl endpoint status --endpoints=http://etcd-2.etcd-headless.default.svc.cluster.local:2380,http://etcd-1.etcd-headless.default.svc.cluster.local:2380,http://etcd-0.etcd-headless.default.svc.cluster.local:2380 -w table. Thanks for sharing your experience everyone! To sum up, I might have got my cluster into a weird state when scaling down to 0 pods while one of the pods was still in a crashloop. Or is this something that etcd will change on its own? That's great! vars. We will close the rest of the existing issues just to avoid duplications, please visit the above-mentioned issue to see any new (when possible . I had 3 initially, and then I scaled down to 2 (still majority), but granted the third node managed to send member removing signal to all the other nodes (1, 2) it should not matter, right? etcd 10:44:26.03 INFO ==> Updating member in existing cluster Error: bad member ID arg (strconv.ParseUint: par. (See the logs below) Logs (etcd-0 node) Vulnerabilities scanner. Although 2 nodes it's not ideal for consensus, you should be able to scale back to 3 nodes if the "member removal" command worked as expected. I am using Helm version 3.1.3, by the way. [bitnami/etcd] Release 8.5.8 updating components versions Signed-off-by: Bitnami Containers <bitnami-bot@vmware.com> * Update README.md with readme-generator-for-helm . This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. IMO the choice to set these two env vars in running containers permanently was unfortunate and it's the most common reason why cluster becomes unstable (i.e. etcd is widely used in production on account of its reliability, fault-tolerance and ease of use. Do not hesitate to reopen it later if necessary. Thanks for the feedback. Additional resources Documentation Obtain credentials Support More on Etcd packaged by Bitnami Create an etcd cluster This section describes the creation of a Etcd cluster with servers located on different hosts. Try Bitnamis etcd Cluster solution, which configures multiple etcd nodes to work together and enable failure-resistant storage for critical application data. Tested with juvd/bitnami-docker-etcd:pr-21-3.5.0-debian-10-r61 image, bitnami/bitnami-docker-etcd#21 almost fixes the missing member_id, but it won't address the issue with pods going CrashLoopBack during scaling. ***> wrote: Just to double check what's going on there Then, you can kill the pods so they are restarted and use the new script. ls /bitnami/etcd/data/ @dk-do could you please also give a try to the instructions I shared? The plugin helps the user to perform ETCD backup and restore of OCP clusters. If the user has lost nodes, they must recreate all the non-recovery control plane machines and then run '-p' option from this plugin to redeploy ETCD. Let me start by saying there is not one single cause for this, there are rather a number of scenarios that could result in cluster instability. Having now a reliable cluster trusted list of nodes, you can parse the output above to build the ETCD_INITIAL_CLUSTER list + add the new member hostname to it. chart-1629734060-etcd-1.log bitnami/ etcd on Docker Hub 3.4.4-debian-10-r8 react-native-navigation on Node.js Yarn 6..1-snapshot.840 . helm repo add bitnami https://charts.bitnami.com/bitnami helm install my-release bitnami/etcd # Read more about the installation in the Etcd packaged by Bitnami Chart Github repository Prerequisites A Kubernetes 1.4+ cluster with Beta APIs enabled Helm installed in your cluster Helm CLI installed in your PC Launching On AKS bash Amazon Web Services Public AMIs for Etcd packaged by Bitnami Trademarks: This software listing is packaged by Bitnami. Data Migration helm Kuberneteschart. The initial cluster setup after running helm install with a replicaCount of 3 seems to run fine. They are. I also tried building docker image based on mentioned PR - it does not generate an event that says that pre-stop failed when scaling down, but it does not help re-joining the cluster when scaling up unfortunately. One question: are you respecting the quorum when scaling down? To solve the issue we wanted to restore the backup. If we take a look to the pod definition, we can see this: So basically it's mounting the "restore" PV at /init-snapshot. Please also run the commands below and share the output: This is the piece of code throwing the logs you shared: So it's basically not finding the file /init-snapshot/db. etcd is widely used in production on account of its reliability, fault-tolerance and ease of use. Check this comment that does sth similar [bitnami/etcd] Restore Issues on Kubernetes #7 (comment) Use kubectl cp to copy your local snapshot to the container (in the path where you mounted the PV) Delete the pod. I'm going to create an internal task to investigate this issue. Check this comment that does sth similar. We will start working on this ASAP, @aavandry. Releases around helm/bitnami-aks/redis 9.3.3 on Artifact Hub. Hi @juan131, I am scaling in/out directly on a statefulset for testing purposes. All three pods have a different member_id. i have the same issue. Method 1: Backup and restore data using etcd's built-in tools. Launch Etcd packaged by Bitnami with one click from the Bitnami Launchpad for Google Cloud Platform . Getting started Understand the default port configuration Obtain application and server credentials Understand the default configuration You mentioned "post-upgrade" hooks but that's not a possibility we're willing to explore for a very simple reason: Bitnami charts are widely used and many users do NOT use helm to manage their apps. This is why we copy the restored data to the original path. I'll create a task to work on it. Overview of Etcd Trademarks: This software listing is packaged by Bitnami. Now, etcd makes use of these env vars only to start a new member after that member has been added to the existing cluster. It seems I am having trouble with this part of the setup.sh: Although when I manually execute the "find snapshot" part, I see my snapshot. You can find the logs attached for this scenario. You signed in with another tab or window. I'd rather start new nodes fresh and sync the latest data. Successfully merging a pull request may close this issue. Our application containers are designed to work well together, are extensively documented, and like our other application formats, our containers are continuously updated when new versions are made available. I'm glad you were able to restore the cluster @mjrepo2. 3 EFS volumes are mounted, but only 2 member_id files have data -. helm install test -f etcd.yaml bitnami/etcd --set statefulset.replicaCount=3 --set persistence.enable=true --set persistence.size=8Gi --set startFromSnapshot.enabled=true --set startFromSnapshot.existingClaim=etcd-snapshotter --set startFromSnapshot.snapshotFilename=/snapshots/db-test.

That said, it's not possible with the current implementation. member new_member_envs. except etcd. @Lavaburn can you confirm that file is also empty in your case? Latest Release Information Download Velero Disaster Recovery Reduces time to recovery in case of infrastructure loss, data corruption, and/or service outages. I understand your point, but I am not totally sure about how to implement that. Sometimes we get these errors: The text was updated successfully, but these errors were encountered: Why are you manually restoring the snapshots? Our application containers are designed to work well together, are I have a follow up question about initialClusterState, should we be setting this flag to existing upon a restore? Time by time we are struggeling with restoring data. That happens because there are container env var changes: ETCD_INITIAL_CLUSTER_STATE changes from new -> existing Launch on more than just a Single VM using etcd Cluster. Please remember to uninstall the previous release previously and remove the PVC(s) generated during the previous installation. In order to use custom configuration parameters, two options are available: Environment variables: etcd allows setting environment variables that map to configuration settings. vars. Yes please, let's continue the conversation in the PR.

Enable this feature with the following parameters: The current cluster is able to restore from failure, but there is no member_id file (not sure whether this is expected). Scaling down with kubectl scale won't re-create remaining nodes, but if you scale-up with kubectl that won't update ETCD_INITIAL_CLUSTER_STATE and ETCD_INITIAL_CLUSTER in statefulset's manifest, so the new nodes that come up won't have the proper ETCD_INITIAL_CLUSTER list (unless you scale-up to the same number of nodes you had initially), Scaling more than one node at a time might cause the cluster to become unstable, that's being discussed in Can't add new member when has three alive member at four member clusteretcd-io/etcd#10738. https://github.com/bitnami/charts/blob/master/bitnami/etcd/README.md, https://github.com/bitnami/charts/blob/master/bitnami/etcd/templates/statefulset.yaml#L131-L138, [bitnami/etcd] Major version: refactoring, https://github.com/bitnami/charts/tree/master/bitnami/etcd#to-600, https://github.com/bitnami/charts-docs/blob/main/charts/etcd/_understand_default_configuration.md.erb, [bitnami/etcd] Issue starting the cluster from startFromSnapshot, Initialize new cluster recovering an existing snapshot, We had a complete power outage in our data centre. When restoring our etcd we have to keep the same deployment name (for connection strings and such), I have noticed when I try to restore a second time, upon helm delete etcd, my PVC for etcd-snapshotter is released, and will not be remounted, since a new PVC/PV for etcd-snapshotter is created.. Is this due to it being labelled as an "init-snapshot-volume" like so ->, init-snapshot-volume: @juan131 Hi, I am using Bitnami/etcd Version 6.8.2 and I have a problem starting the cluster from startFromSnapshot, I uninstalled etcd and re-installed it using the above configurationBut the cluster cannot be recovered, I see you already opened a new issue in our bitnami/charts repository and someone from our team is giving you feedback already, let's move the conversation there . We periodically deploy changes via helm upgrade --install, and hence ETCD_INITIAL_CLUSTER_STATE also transitioned for us at some point from new to existing. To resolve my issue, I had to clean the persistent volumes. It should be "new", since "existing" should be only used when a node is joining a running cluster. It eventually fixed itself after 4 retries though, which is good. /opt/bitnami/scripts/etcd/prestop.sh for example. etcd is widely used in production on account of its reliability, fault-tolerance and ease of use. If we face some problems in our QA-stage we transfer all databases (Mongo, Elastic, PSQL, etcd, Redis) to our dev-stage to investigate the problem. I did some further investigation and was finally able to get the cluster up. Launch as many etcd instances as the number of nodes you wish to have in your cluster (in this example, three instances) and then perform the steps below on each node: chart-1629734060-etcd-2.log RabbitMQ AMQP RabbitMQErlang AMQPAdvanced Message Queue AMQP (Reliablity) (Flexible Routing) Exchange Well occasionally send you account related emails. Network Policy 3. Helm. Sign in Deploying Bitnami applications as containers is the best way to get the most from your infrastructure. We are seeing that the cluster state is always new, upon restore, or upon upgrade, or upon restarting etcd pods. Which is even weirder is, that there is a moment before the container restarts, where I can check the contents of /init-snapshot/ with kubectl containing the snapshot. If everything goes according to plan, we will start working on this issue next week. Once a day we copy the data from the etcd-snapshot directory to a backup folder in filesystem to perform a tape backup. After following the conversation on a similar sounding issue (#3190), I did some debugging around the creation of the ${ETCD_DATA_DIR}/member_id file. In order to set extra environment variables, use the extraEnvVars property (shown in the example below). Now it gets funny, the etcd cluster builds up fine and everything is ok until every-day at 5:00 am, at this time the 3rd member of the cluster is leaving the cluster, the second node just stays fine. [bitnami/etcd] Restore Issues on Kubernetes. Instead, we could improve the logic inside the libetcd.sh script to make it smarter and capable of distinguish when to ignore the values set on these env. Subsequently, a major version of the chart was released to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL. move ETCD_INITIAL_CLUSTER_STATE and ETCD_INITIAL_CLUSTER outside container variables, instead handle these inside the libetcd.sh script. In other words existing cluster members are informed of the new addition via etcdctl member add, then it's only the newly added member that should be made aware of, hey, you get added to an existing cluster and this is the list of node URLs including yours. Or do I have to always provide another extra volume for that? Releases around bitnami/etcd 3.4.4-debian-10-r8 on Docker Hub. Now you have a PV containing your local snapshot. I mean, we are already providing mechanisms in the chart to automatically recover them installing a new chart. It is expected that setting initialClusterState to existing would resolve this. The current state of the helm chart is basically unusable as far as I can tell, as any pod crash will lead to a infinite crash loop or am I missing something? Bitnami's Best Practices for Securing and Hardening Helm Charts, Backup and Restore Apache Kafka Deployments on Kubernetes, Backup and Restore Cluster Data with Bitnami and Velero. Download virtual machines or run your own etcd server in the cloud. This would not only prevent remaining nodes to be re-created but it would also make it possible to scale properly using kubectl scale. Etcd packaged by Bitnami etcd is a distributed key-value store designed to securely store data across a cluster. A tag already exists with the provided branch name. The Bitnami Library for Kubernetes Popular applications, provided by Bitnami, ready to launch on Kubernetes using Kubernetes Helm. On November 13, 2020, Helm v2 support formally ended.

The respective trademarks mentioned in the offering are owned by the respective companies, and use of them does not imply any affiliation or endorsement. Copy the db file to /tmp/ to all etcd-0, etcd-1, etcd-2 pods. When cluster moves to existing state, the member_id file became empty, so a POD can not start.
